issues regarding https://jira.springframework.org/browse/SWF-1383 fix [SWF-1391]

[spring-operator]

James opened SWF-1391 and commented

After the fix, I can start my application. The home page is a non-swf request. So the original issue is fixed. But after I login, I can not start spring web flow. I got the following exceptions.

It looks like your FacesContext is null. It's probably because you'r missing some configuration. Please, see booking-faces sample configuration. Specifically the FlowFacesContextLifecycleListener in webflow-config.xml.

I replaced with SWF 2.1 jar files. Everthing works fine. I am trying to invoke SWF from Spring MVC at this point. Since I cannot start SWF directly from faces-config.xml navigation redirect, I first redirect to a html page via Spring MVC servlet from faces-config.xml and then redirect to SWF from that page. It will be nice if SWF support redirect from faces-config.xml navigation.

See the exception.

org.springframework.webflow.execution.FlowExecutionException: Exception thrown in state 'donorLoginHome' of flow 'donorLogin'

donorLoginHome is the first state in my donorLogin.xml flow definiton.

Unless you have any further comments on the original description of this issue, I am going to close it. The issue is most likely due to missing FlowFacesContextLifecycleListener configuration.

James commented

You are right. This issue can be closed. thanks.

Rossen Stoyanchev commented

Closing this issue as it doesn't appear to be a bug. FWIW there are plans to make this configuration easier for 2.2.0.RC1 #561.
